Official Title ICMJE

The Effect of Active Warming in Prehospital Trauma Care During Road and Air Ambulance Transportation - a Clinical Randomized Trial

Brief Summary

Prevention and treatment of hypothermia by active warming in prehospital trauma care is recommended but scientifical evidence of its effectiveness in a clinical setting is scarce. The objective of this study was to evaluate the effect of additional active warming during road or air ambulance transportation of trauma patients.

Patients were assigned to either passive warming with blankets or passive warming with blankets with the addition of an active warming intervention using a large chemical heat pad applied to the upper torso. Ear canal temperature, subjective sensation of cold discomfort and vital signs were monitored.

In mildly hypothermic trauma patients, with preserved shivering capacity, adequate passive warming is an effective treatment to establish a slow rewarming rate and to reduce cold discomfort during prehospital transportation. However, the addition of active warming using a chemical heat pad applied to the torso will significantly improve thermal comfort even further and reduce the cold induced stress response.

Eligibility Criteria ICMJE

Inclusion Criteria:

Subjects were sequential trauma patients, age ≥ 18 years, who had sustained an injury outdoors and were transported by one of the participating EMS units.

Exclusion Criteria:

Patients were excluded if initial level of consciousness was affected, (Glasgow Coma Scale < 15), if they required prehospital CPR or if duration of transportation was expected to be shorter than 10 minutes.

As the aim of the study was to investigate the effect of active warming intervention in cold stressed patients, those patients who had already received active warming or had been taken indoors for more than 10 minutes before EMS unit arrival or had an initial cold discomfort rating ≤ 2 were also excluded.
